Patent number: 7332062Abstract: An electroplating tool for providing a metal or metal film on a semiconductor wafer during processing thereof has a wafer chucking mechanism with a conductor or conductors associated therewith. The conductor(s) are electrically connected to a controller that applies a voltage or current applied thereto for altering the position of and/or varying the intensity of electromagnetic field lines originating from a source anode of the electroplating tool. The electromagnetic field lines originating from the source anode direct the deposition of metal from the electroplating solution to the semiconductor wafer. The conductor(s) of the wafer chucking mechanism improve and/or modulate the electromagnetic field lines of the electroplating process. This provides greater control of metal deposition during the electroplating process such that uniformity of the metal (e.g. copper) is provided across the semiconductor wafer.Type: GrantFiled: June 2, 2003Date of Patent: February 19, 2008Assignee: LSI Logic CorporationInventors: Steven E. Reder, Michael J. Berman

Patent number: 7332064Abstract: A hangar bar for a cathode plate and a method of producing a cathode for electrolytic recovery of metal. The hanger bar comprises a support element which is preferably stainless steel and hollow. An electrically conductive metal cladding is affixed the stainless steel bar by any appropriate mechanism, eg interference fit, welding, chemical or mechanical fastening or coextrusion or roll forming. Affixing the cladding to the stainless steel support element has significant advantages over conventional electroplating techniques including that a more precise engineering specification can be applied to the cladding thickness. This is important to maintain vertical alignment of the cathode plate in the electrolytic cell.Type: GrantFiled: January 28, 2003Date of Patent: February 19, 2008Assignee: Mount Isa Mines LimitedInventor: Wayne Keith Webb

Patent number: 7332066Abstract: A process for metallization of a workpiece, such as a semiconductor workpiece. In an embodiment, an alkaline electrolytic copper bath is used to electroplate copper onto a seed layer, electroplate copper directly onto a barrier layer material, or enhance an ultra-thin copper seed layer which has been deposited on the barrier layer using a deposition process such as PVD. The resulting copper layer provides an excellent conformal copper coating that fills trenches, vias, and other microstructures in the workpiece. When used for seed layer enhancement, the resulting copper seed layer provide an excellent conformal copper coating that allows the microstructures to be filled with a copper layer having good uniformity using electrochemical deposition techniques. Further, copper layers that are electroplated in the disclosed manner exhibit low sheet resistance and are readily annealed at low temperatures.Type: GrantFiled: February 7, 2005Date of Patent: February 19, 2008Assignee: Semitool, Inc.Inventors: Linlin Chen, Gregory J.

Patent number: 7332067Abstract: A process for the preparation of ?-substituted carboxylic acids from the series including ?-hydroxycarboxylic acids and N-substituted-?-aminocarboxylic acids by cathodic carboxylation with carbon dioxide of a compound corresponding to the general formula R1—C(?X)R2 which is constituted by aldehydes, ketones or N-substituted imines. In the past, that carboxylation has taken place in an undivided electrolytic cell with the use of a sacrificial anode. As described herein, the carboxylation takes place in the absence of a sacrificial anode in an electrolytic cell divided by a separator, at a diamond film cathode. The anode is formed of a material which is stable under electrolytic conditions; in particular, it is a diamond film electrode. The catholyte includes an organic solvent and a conducting salt.Type: GrantFiled: June 3, 2004Date of Patent: February 19, 2008Assignee: Degussa AGInventors: Christian Reufer, Martin Hateley, Thomas Lehmann, Christoph Weckbecker, Rainer Sanzenbacher, Jürgen Bilz

Patent number: 7332068Abstract: A metal is provided on a polymeric component and the component is subjected to a removal process such as plasma or liquid etching in the presence of an electric field. The etchant selectively attacks the polymer at the boundary between the metal and the polymer, thereby forming gaps alongside the metal. A cover metal may be plated onto the metal in the gaps. The cover metal protects the principal metal during subsequent etching procedures.Type: GrantFiled: May 28, 2004Date of Patent: February 19, 2008Assignee: Tessera, Inc.Inventors: Belgacem Haba, Irina Poukhova, Masud Beroz
